Serial# F0140967 cooresponds to the 40967th guitar made in 2001 at the Fujigen factory in Japan.
Beautiful guitar btw. I looked (cursorily) through the 2001 and 2002 catalogues but wasn't able to find it, maybe if you take a close look you can:

If you take off the neck and look in the neck pocket, there may be a stamp on either the body or neck indicating what model it is.
